Product Profile:

The function of the rectifier transformer is to connect to the AC/DC power converter, convert the power side voltage to the voltage required for the load, and provide electrical isolation between the load and the power supply side.According to IEC-146, circuit 2/8/10/15/19, only one 2 side winding transformer (connection group DYn11), suitable for operation in the 6 pulse rectifier.According to IEC-146, 3/4/5/6/11/12/16/17/18 circuit, transformer with two windings (2 side connection group Dd0y11), electromagnetic decoupling, suitable for operation in the 12 pulse rectifier, 12 pulse rectifier, which consists of two parallel connected 30 phase bridge circuit.

Product features:

The insulation system conforms to UL1446, and can also be designed according to user's requirements.The temperature rise conforms to the H grade, and the insulation material adopts H grade.The transformer is immersed in an insoluble polyester resin under vacuum pressure (VPI) and cured in thermal curing.The transformer is generally designed as natural air cooling, and forced air cooling can be designed according to user requirements. At this time, the shape, size and weight of the transformer will be reduced.At this time, it is recommended to use air-cooled devices to ensure the operation of transformers (especially large capacity transformers).Product testing:100% product testing.
